Guideline on safe handling on self-contained air-to-water residential heat pumps with refrigerants with higher flammability installed outdoors in Europe
We are pleased to share the first edition of our guideline, now available online. This document focuses on the safe handling of self-contained air-to-water heat pumps (AWHP) designed for outdoor installation in single-family homes, specifically those using refrigerants with higher flammability, such as R-290.
Following the adoption of the revised F-gas Regulation (EU) 2024/573, the market has seen a rise in heat pumps using non-fluorinated refrigerants. While these alternatives are more climate-friendly, they may also present increased flammability risks—making proper handling essential. This guideline outlines key legal, normative, and technical considerations to support the safe and responsible management of these systems.
The intended audience includes manufacturers, installers, plumbers, and other professionals involved at any stage of the product’s lifecycle—from production to end-of-life. While this document is not designed for end-users, we strongly encourage homeowners to consult with a qualified professional or their service provider for any questions or concerns.
